In two phase I-II trials, 33 patients were given recombinant interferon alpha-2 daily at dosages of 3, 10, 30, 50, or 100 MU/d for up to 4 weeks by intramuscular or intravenous routes. Dose-limiting toxicities, including neutropenia, elevated hepatocellular enzyme levels, fatigue, and disturbed mentation, correlated with differing serum pharmacokinetics of interferon in the two trials. In the intramuscular study, dose-limiting toxicity occurred at all dosages greater than 10 MU/d, at a median of 6 to 9 days of treatment. In the intravenous dose-study, limiting toxicity was seen only at dosages of 100 MU/d, at a median of day 8. Twenty-three patients had metastatic melanoma and 4 had objective partial or complete responses at dosages of 10 to 50 MU/d in the first month. Two patients with complete responses are free of tumor after 2.5 years of follow-up. A fifth patient had delayed complete regression, requiring 1 year to achieve maximum response, but remains free of disease at 26 months since entry to the trial. Interferon had antitumor activity against melanoma by both routes tested, at dosages of 10 to 50 MU/d.

Twenty-six adult patients were entered in a phase I trial of carboplatin, a new cisplatin derivative with reduced potential for nephrotoxicity. All patients had solid tumors and the median World Health Organization performance score was 2 (0-3). Twelve patients had not received prior chemotherapy. The drug was administered as a 15-minute IV infusion, without pre- or posthydration, at daily doses of 40-125 mg/m2 for five consecutive days. Antiemetics were given only if needed. Thrombocytopenia and neutropenia were dose related and dose limiting. One patient died from septic shock at the highest dose level. Nonhemolytic anemia was also encountered. Nausea and vomiting were experienced by most patients but gastrointestinal intolerance was severe in only two patients. One patient had hypercreatininemia, which was minor and rapidly reversible. Other toxic effects consisted of negligible fatigue, paresthesia, pruritus, local pain, stomatitis, headache, and alopecia. Although none of the patients achieved a partial or complete response, antitumor effect was strongly suggested in two patients with thyroid and cervix cancer, respectively. Carboplatin is an attractive candidate for phase II trials. In good-risk patients, such trials could be initiated at a daily dose of 100 mg/m2 for five consecutive days every five to six weeks.

Complement (C) activation, neutropenia, and mild pulmonary dysfunction attend hemodialysis (HD) with cellophane [for example, cuprophan (Cu)] membranes. While usually asymptomatic, these phenomena may cause distress in patients with cardiopulmonary disease, and "start-up" symptoms of HD might be mediated by C-stimulated granulocytes (PMNs). Cellulose acetate (CA) hemodialysis membranes have been devised and claimed more blood compatible than Cu. In a blinded series of HD patients, pruritus, fatigue, and sense of well-being were each scored statistically more favorably by the patients during HD with CA than during HD with Cu (P less than 0.05). Postulating that less C activation might underlie the benefit, we showed that neutropenia was less severe with CA (nadir 77.6% of initial count, +/- 4 SEM) than with Cu (38.3% +/- 2.9; P less than 0.01). In vitro, incubation of CA membranes with plasma led to less C3 conversion (20% vs. 40%), less PMN aggregating activity (5.9 ZAP units vs. 36.3) and less decrement in CH50 (6.5% vs. 22%) than like incubations of Cu. C activation was also less potent in vivo: During HD plasma C3a rose from a mean 401 ng/ml to a peak 6,325 in patients on Cu dialyzers, but from 426 to only 3,637 in patients on CA devices (P less than 0.05). Time-course studies suggested CA was initially as potent an activator as Cu but rapidly lost ability to activate C, possibly because of saturation of C3b binding sites. As an index of PMN activation, we also assayed plasma lactoferrin and found levels significantly higher during Cu than CA dialysis.(ABSTRACT TRUNCATED AT 250 WORDS)

Intraperitoneal (IP) administration of fluorinated pyrimidines has been evaluated for ovarian and gastrointestinal malignancies in phase I, II, and III trials. The tolerance and pharmacokinetic profile of IP 5-fluoro-2'-deoxyuridine(FUDR) alone and with (R,S)-leucovorin ((R,S)-LV) have each been evaluated in previous phase I studies. FUDR doses of 3 g per day with and without (R,S)-LV doses up to 640 mg per day given IP are well tolerated. The current phase I study was designed to determine the pharmacokinetic profiles and clinical tolerance of escalating doses of the pure biologically active S-isomer of leucovorin ((S)-LV) given IP with the same dosing schedule of FUDR. A group of 16 patients with disease confined to the abdominal cavity were treated in this study. Pharmacokinetic studies of blood and peritoneal fluid, toxicity profiles, and clinical response for the first three cycles are reported here. The toxicity profile did not significantly differ from the prior two studies. All non-hematologic toxicities, such as fatigue, nausea, vomiting, diarrhea, and abdominal discomfort were less than grade 4, and most were less than grade 3. Neutropenia and thrombocytopenia were uncommon and observed only in patients with compromised bone marrow reserve. The pharmacokinetic profiles were also congruent with the previous studies and indicate a three-log advantage for FUDR. The (S)-LV profiles in the peritoneal cavity paralleled those of FUDR. Antitumor effects or absence of progression until after cessation of therapy were documented in 11 patients. At a median follow-up of 18 months 44% of patients were alive. IP administration of 3-g of FUDR and up to 640 mg (S)-LV daily for three days was well tolerated. The tolerance and antitumor effects observed during IP FUDR and LV in these studies encourage further exploration of this regimen against ovarian and gastrointestinal malignancies. The actual role and optimal dose of LV as an enhancer of the antitumor actions of FUDR administered by this route remain unknown.

Several clinical trials have demonstrated that granulocyte colony-stimulating factor (G-CSF) accelerates the recovery of neutropenia in chemotherapy-induced bone marrow suppression. In this report, we describe a 46-year-old female with glioblastoma multiforme who developed interstitial pneumonia due to administration of G-CSF during the phase of immunochemoradiotherapy-induced neutropenia. Thirty-three days after starting immunochemoradiotherapy (ACNU, VCR, IFN -beta, radiation), she developed neutropenia (1,000/microliters). Administration of G-CSF at doses of 125-250 micrograms/day led to an increase of peripheral neutrophil counts. Eleven days later, the patient developed sudden severe respiratory failure and cyanosis with worsening of lung shadows. Blood gas levels on room air were PaO2 49.3mmHg, PaCO2 28.0mmHg, and pH 7.46. At this time, her neutrophil count had risen to 26,080/microliters. LDH and alpha - HBD had also increased to 1,439 IU/l and 1,117IU/l respectively. Chest radiograph and CT scan demonstrated interstitial pneumonia. After treatment with methyl prednisolone, her respiratory symptoms were gradually resolved. A number of side-effects have been reported with granulocyte-macrophage colony-stimulating factor (GM-CSF). These include fluid retention with pericardial and pleural effusion, fever, bone pain, fatigue, and rash. This report also suggests that G-CSF might be a cause of interstitial pneumonia during the phase of immunochemoradiotherapy-induced neutropenia.

Since their initial description in 1957, the interferons (IFNs) have been increasingly used to treat a wide array of diseases. Acute adverse effects, i.e. 'flu-like' syndromes, hypo- or hypertension, tachycardia, headache, myalgias and gastrointestinal disorders, occur within the first hour or day after starting treatment. They are seldom treatment-limiting and are easily manageable. Sub-acute and chronic effects develop after several days, usually within 2 and 4 weeks of therapy. The most typical is neurological toxicity, including fatigue/asthenia, and behavioural and cognitive changes. Such symptoms may seriously impair quality of life and result in treatment discontinuation. Seizures have seldom been described. Other infrequent central nervous system adverse effects include vertigo, cramp and oculomotor nerve paralysis. Distal paraesthesias and peripheral neuropathy have been reported. IFN-associated autoimmunity is quite rare but a matter of concern. Biological or clinical manifestations usually require several months to become apparent. Autoantibodies have been shown to develop in most patients but have been inconsistently associated with clinical symptoms of systemic lupus erythematosus, rheumatoid-like arthritis and thyroiditis. Both hypo- and hyperthyroidism have been described but are usually reversible. Other infrequent autoimmune reactions include diabetes, pemphigus and worsening of multiple sclerosis. Although several patients present with a pre-existing autoimmune disorder, no predisposing factor has been clearly established. While hypotension and tachycardia are the most frequent acute cardiovascular complications, a few additional cases of cardiac arrhythmias and myocardial ischaemia have been reported after a short course or several weeks of treatment. These latter complications do not appear to be dose-dependent or age-related. Isolated cases of congestive heart failure have also been described. Mild proteinuria has been observed in 15 to 25% of patients, but acute renal toxicity is uncommon. A transient rise in serum aminotransferase levels is frequently noted during the first stage of therapy, especially in patients receiving the highest dosages. Direct hepatotoxicity is extremely rare. Autoimmune hepatitis, which is ill-diagnosed as chronic viral hepatitis, and de novo induction of autoimmune hepatitis, account for the majority of liver diseases. Haematotoxicity is relatively common but mild to moderate, and develops gradually during the first weeks of treatment. Neutropenia is the most common haematological toxicity, but is usually not dose-limiting and resolves rapidly upon drug discontinuation. Myelosuppression, autoimmune and immune allergic haemolytic anaemias and thrombocytopenias have seldom been described. Cutaneous adverse effects comprised nonspecific erythema and hair loss and, less frequently, vasculitis, local ulcerations at the site of injection and exacerbation of psoriasis.(ABSTRACT TRUNCATED AT 250 WORDS)

A phase II trial of combination paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) and carboplatin included 54 chemotherapy-naive patients with advanced non-small cell lung cancer. Eligibility mandated Eastern Cooperative Oncology Group performance status of 0 or 1 and adequate hematologic, renal, and hepatic function. Paclitaxel 135 mg/m2 over 24 hours preceded carboplatin dosed to an area under the concentration-time curve of 7.5. Six planned courses were given every 3 weeks. Granulocyte colony-stimulating factor was introduced during the second and subsequent cycles, and paclitaxel increased 40 mg/m2/cycle (maximum, 215 mg/m2) in patients with absolute neutrophil and platelet nadirs exceeding 500/microL and 50,000/microL, respectively. Grade 3 or 4 neutropenia, observed in 54% of patients during cycle 1, declined to 35% during cycle 2 and to 22% or less during cycles 3 through 6. Neuropathy, myalgias/arthralgias, and thrombocytopenia were mild but cumulative. In 53 evaluable patients, the objective response rate was 62%, with 9% complete remissions and a median response duration of 6 months (range, 1 to 19+ months). At median potential follow-up of 16 months, 9% of patients remain progression free (52+ to 80+ weeks). Median survival is 12.5 months; 1-year survival is 54%. Paclitaxel/carboplatin is highly active in advanced non-small cell lung cancer; granulocyte colony-stimulating factor abrogates neutropenia as the dose-limiting toxicity, but has no effect on the cumulative incidence of thrombocytopenia or treatment delays. One-hour paclitaxel infusion is minimally myelosuppressive, logistically easier, and less costly. A follow-up study combined paclitaxel (175 mg/m2) over 1 hour followed by carboplatin (area under the concentration-time curve, 7.5). In the absence of grade 4 myelosuppression, paclitaxel was increased 35 mg/m2/cycle (maximum, 280 mg/m2). Granulocyte colony-stimulating factor was implemented only after neutropenic fever or grade 4 neutropenia. Of 17 patients entered, 13 are evaluable for toxicity and seven for response. Four patients have sustained a partial response, two a minor response, and one stable disease. The incidence of grade 3 or 4 neutropenia, thrombocytopenia, and anemia in cycle 1 was 38%, 16%, and 0%, respectively, and 72%, 28%, and 28%, respectively, during cycle 2. Major nonhematologic toxicities include myalgias and arthralgias (54%) and fatigue and neuropathy (78%), the latter cumulative and progressive over successive cycles. Preliminary data suggest comparable activity for the 1- and 24 hour paclitaxel infusions in combination with carboplatin. The more severe neuropathy of the 1-hour paclitaxel/carboplatin combination may be related to the paclitaxel dosing schema (175 mg/m2 to as high as 280 mg/m2).(ABSTRACT TRUNCATED AT 400 WORDS)

An ongoing phase I/II trial in patients with chemotherapy-naive metastatic breast cancer (one adjuvant chemotherapy regimen is allowed) uses a 3-hour infusion of paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) 90 mg/m2 followed by a 3-hour infusion of cisplatin 60 mg/m2 every 2 weeks given with standard premedications. The protocol called for the escalation of paclitaxel in 10 mg/m2 increments to as much as 130 mg/m2 combined with a fixed 60 mg/m2 cisplatin dose without granulocyte colony-stimulating support in the phase I portion of the trial, but dose-limiting neutropenia identified the initial 90 mg/m2 paclitaxel dose as the maximum tolerated in this biweekly schedule. The phase II portion is continuing to accrue patients and results are preliminary. Twenty-two patients have been enrolled thus far. Of the 16 evaluable for response, four (25%) have had a complete and II (69%) a partial response, for an overall response rate of 94%. Eighteen patients are evaluable for toxicity. Significant neutropenia has been dose limiting, but the mean duration of the absolute neutrophil nadir (< 0.5 x 10(9)/L) is only 2 days. Nonhematologic toxicity has been generally mild, with no grade 4 and few grade 3 toxicities occurring. Nausea, most likely attributable to cisplatin, has occurred frequently, as have mild hypersensitivity reactions. Other nonhematologic toxicity (arthralgias, fatigue, neurologic symptoms) also has been mild.

One hundred and seven previously untreated patients with measurable metastatic colorectal cancer who were treated with 5-fluorouracil (5FU) and leucovorin (LV) in two different maximum doses and schedules were retrospectively analyzed. Group A, 52 pts, was treated with LV 200 mg/m2/D i.v. push, followed by 5FU 700 mg/m2/D i.v. 1 h infusion for 5 D. Cycle was repeated every 21 D. Group B, 55 pts, was treated with LV 500 mg/m2/D in a 2 h infusion and 5FU 600 mg/m2/D i.v. bolus at mid-time of LV infusion, repeated every week for 6 wk followed by 2-wk rest period. There was no difference in response (A 8%, B 11%). Median survival for A was 37 (2-131) wk, B was 59 (1-112) wk (P = 0.021), time to progression for A was 20 (0-131) wk, B 30 (0-102) wk (P = 0.021). Administered mean dose intensity of LV was 350.8 mg/m2/wk in group A and 405.0 mg/m2/wk in group B without any significant difference; that of 5FU was significantly higher in group A as compared to group B (1205.3 vs 468.9 mg/m2/wk, respectively) (p < 0.0001). This difference was a consequence of the planned dose intensity for this drug in the two treatment regimens. Toxicity was more frequent and intense in group A for mucositis (P < 0.001), fatigue (P < 0.01), and neurotoxicity (P < 0.05), and in group B for neutropenia (P < 0.001) and nausea-vomiting (P < 0.001). There were one and four iatrogenic deaths in group A and B patients, respectively (NS).(ABSTRACT TRUNCATED AT 250 WORDS)

The antitumour activity of docetaxel was investigated in patients with advanced malignant melanoma. Docetaxel, 100 mg/m2, intravenous, over 60 min, was administered every 3 weeks. Response evaluation was performed after two cycles. No prophylactic treatment with steroids or antihistamines was given. 38 patients were included, 36 were eligible and evaluable for toxicity and 30 patients were evaluable for response. The main haematological toxicity was neutropenia [17 patients with common toxicity criteria (CTC) grade 4 and 11 CTC grade 3] with nadir after 5-8 days and rapid recovery. The most frequent non-haematological toxicity was generalised alopecia (83% of the patients). Asthenia, malaise and fatigue were also seen in 58%. Skin toxicity was also frequent. Hypersensitivity reactions (erythematous rash, urticaria, blood pressure changes and tachycardia), seen in 42% of the patients, were mild to moderate. Oedema was registered in one fifth of the patients and developed after four or more treatment cycles. The overall response rate in the evaluable patients was 17% (five partial responders). We conclude that docetaxel has activity in advanced malignant melanoma.
